These papers summarize the most exciting new results in the field of cosmic ray physics and detail their importance to the larger fields of astrophysics and high energy physics. Some of the topics included are cosmic rays, solar physics, high energy particles, neutrinos, gamma rays, astroparticle physics, cosmology, and experimental techniques.




Solar Cosmic Rays


Book Description

Presents a comprehensive approach to the open questions in solar cosmic ray research and includes consistent and detailed considerations of conceptual, observational, theoretical, experimental and applied aspects of the field. The results of solar cosmic ray (SCR) investigations from 1942 to the present are summarized in this book. It treats the research questions in a self-contained form in all of its associations, from fundamental astrophysical aspects to geophysical, aeronautical and cosmonautical applications. A large amount of new data is included, which has been accumulated during the last several decades of space research. This second edition contains numerous updates and corrections to the text, figures and references. The author has also added several new sections about GLEs and radiation hazards. In addition, an extensive bibliography is provided, which covers non-partially the main achievements and failures in the field. This volume is aimed at graduate students and researchers in solar physics and space science.







Particle Physics and the Universe


Book Description

It is generally felt in the cosmology and particle astrophysics community that we have just entered an era which later can only be looked back upon as a golden age. Thanks to the rapid technical development, with powerful new telescopes and other detectors taken into operation at an impressive rate, and the accompanying advancement of theoretical ideas, the picture of the past, present and future Universe is getting ever clearer. Some of the most exciting new findings and expected future developments are discussed in this invaluable volume. The topics covered include the physics of the early Universe and ultra-high energy processes. Emphasis is also put on neutrino physics and astrophysics, with the evidence for non-zero neutrino masses emerging from both solar neutrinos and atmospheric neutrinos covered in great depth. Another field with interesting new results concerns the basic cosmological parameters, where both traditional methods and the potential of new ones, like deep supernova surveys and acoustic peak detections in the cosmic microwave background, are thoroughly discussed. Various aspects of the dark matter problem, such as gravitational lensing estimates of galaxy masses, cluster evolution and hot cluster electron distortions of the thermal microwave background spectrum, are also discussed, as are particle physics candidates of dark matter and methods to detect them. Cosmic rays of matter and antimatter are included as a topic, and so is the problem of the enigmatic dark energy of the vacuum. Contents: Cosmology with Clusters of Galaxies (N A Bahcall); Radiochemical Solar Neutrino Experiments and Implications (T A Kirsten); Evidence for Neutrino Oscillation Observed in Super-Kamiokande (Y Totsuka); High Energy Cosmic Neutrinos (S W Barwick); Discovery of the Cosmic Microwave Background (D T Wilkinson & P J E Peebles); Starlight in the Universe (P Madau); Acceleration of Ultra High Energy Cosmic Rays (R D Blandford); Dark Matter and Dark Energy in the Universe (M S Turner); Dark Matter Tomography (J A Tyson); Status of Models for Gamma Ray Bursts (M J Rees); and other papers. Readership: High energy physicists, astrophysicists and cosmologists.




The Century of Space Science


Book Description

One of the most attractive features of the young discipline of Space Science is that many of the original pioneers and key players involved are still available to describe their field. Hence, at this point in history we are in a unique position to gain first-hand insight into the field and its development. To this end, The Century of Space Science, a scholarly, authoritative, reference book presents a chapter-by-chapter retrospective of space science as studied in the 20th century. The level is academic and focuses on key discoveries, how these were arrived at, their scientific consequences and how these discoveries advanced the thoughts of the key players involved. With over 90 world-class contributors, such as James Van Allen, Cornelis de Jager, Eugene Parker, Reimar Lüst, and Ernst Stuhlinger, and with a Foreword by Lodewijk Woltjer (past ESO Director General), this book will be immensely useful to readers in the fields of space science, astronomy, and the history of science. Both academic institutions and researchers will find that this major reference work makes an invaluable addition to their collection.




Eleventh Marcel Grossmann Meeting, The: On Recent Developments In Theoretical And Experimental General Relativity, Gravitation And Relativistic Field Theories (In 3 Volumes) - Proceedings Of The Mg11 Meeting On General Relativity


Book Description

The Marcel Grossmann Meetings are three-yearly forums that meet to discuss recent advances in gravitation, general relativity and relativistic field theories, emphasizing their mathematical foundations, physical predictions and experimental tests. These meetings aim to facilitate the exchange of ideas among scientists, to deepen our understanding of space-time structures, and to review the status of ongoing experiments and observations testing Einstein's theory of gravitation either from ground or space-based experiments. Since the first meeting in 1975 in Trieste, Italy, which was established by Remo Ruffini and Abdus Salam, the range of topics presented at these meetings has gradually widened to accommodate issues of major scientific interest, and attendance has grown to attract more than 900 participants from over 80 countries.This proceedings volume of the eleventh meeting in the series, held in Berlin in 2006, highlights and records the developments and applications of Einstein's theory in diverse areas ranging from fundamental field theories to particle physics, astrophysics and cosmology, made possible by unprecedented technological developments in experimental and observational techniques from space, ground and underground observatories. It provides a broad sampling of the current work in the field, especially relativistic astrophysics, including many reviews by leading figures in the research community.




Production Yield of Muon-Induced Neutrons in Lead


Book Description

The work presented in this book is a major step towards understanding and eventually suppressing background in the direct search for dark matter particles scattering off germanium detectors. Although the flux of cosmic muons is reduced by many orders of magnitude in underground laboratories, the remaining energetic muons induce neutrons through various processes, neutrons that can potentially mimic a dark matter signal. This thesis describes the measurement of muon-induced neutrons over more than 3 years in the Modane underground laboratory. The data are complemented by a thorough modeling of the neutron signal using the GEANT4 simulation package, demonstrating the appropriateness of this tool to model these rare processes. As a result, a precise neutron production yield can be presented. Thus, future underground experiments will be able to reliably model the expected rate of muon-induced neutrons, making it possible to develop the necessary shielding concept to suppress this background component.







The Multi-Messenger Approach to High-Energy Gamma-Ray Sources


Book Description

This book provides a theoretical and observational overview of the state of the art of gamma-ray astrophysics, and their impact and connection with the physics of cosmic rays and neutrinos. With the aim of shedding new and fresh light on the problem of the nature of the gamma-ray sources, particularly those yet unidentified, this book summarizes contributions to a workshop that continues today.




The STEREO Mission


Book Description

C. T. Russell Originally published in the journal Space Science Reviews, Volume 136, Nos 1–4. DOI: 10. 1007/s11214-008-9344-1 © Springer Science+Business Media B. V. 2008 The Sun-Earth Connection is now an accepted fact. It has a signi cant impact on our daily lives, and its underpinnings are being pursued vigorously with missions such as the Solar TErrestrial RElations Observatory, commonly known as STEREO. This was not always so. It was not until the middle of the nineteenth century that Edward Sabine connected the 11-year geomagnetic cycle with Heinrich Schwabe’s deduction of a like periodicity in the sunspot record. The clincher for many was Richard Carrington’s sighting of a great whi- light are on the Sun, on September 1, 1859, followed by a great geomagnetic storm 18 hours later. But was the Sun-Earth Connection signi cant to terrestrial denizens? Perhaps in 1859 it was not, but a century later it became so. Beginning in the 1930’s, as electrical powergrids grew in size, powercompanies began to realize that they occasionally had power blackouts during periods of intense geomagnetic activity. This correlation did not appear to be suf ciently signi cant to bring to the attention of the public but during the International Geophysical Year (IGY), when geomagnetic activity was being scrutinized intensely, the occurrence of a large North American power blackout during a great magnetic storm was impossible to ignore.
